Caution Regarding Forward-Looking Information; Risk Factors

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Canadian and United States securities laws, including the United States Private Securities Litigation Reform Act of 1995. From time to time, our public filings, press releases, and other communications (such as conference calls and presentations) will contain forward-looking statements. Forward-looking information is often, but not always, identified by the use of words such as “anticipate,” “believe,” “expect,” “plan,” “intend,” “forecast,” “target,” “project,” “may,” “will,” “should,” “could,” “estimate,” “predict,” or similar words suggesting future outcomes or language suggesting an outlook. Forward-looking statements in this Quarterly Report on Form 10-Q include, but are not limited to, statements with respect to expectations of our prospects, future revenue, earnings, activities, and technical results.

Forward-looking statements and information are based on current beliefs as well as assumptions made by, and information currently available to, us concerning anticipated financial performance, business prospects, strategies, and regulatory developments. Although management considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect. The forward-looking statements in this Quarterly Report on Form 10-Q are made as of the date they were issued and we do not undertake any obligation to update publicly or to revise any of the included forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by applicable law.

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks that outcomes implied by forward-looking statements will not be achieved. We caution readers not to place undue reliance on these forward-looking statements as a number of important factors could cause the actual results to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates, and intentions expressed in such forward-looking statements.

These risks and uncertainties include, but are not limited to, the impact of: changes in oil and natural gas prices; worldwide and domestic economic conditions on drilling activity and demand for and pricing of our products and services; other risks inherent in the drilling services industry (e.g. operational risks, potential delays or changes in customers’ exploration or development projects or capital expenditures, the uncertainty of estimates and projections relating to levels of rental activities, uncertainty of estimates and projections of costs and expenses, risks in conducting foreign operations, the consolidation of our customers, and intense competition in our industry); and risks associated with our intellectual property and with the performance of our technology. These risks and uncertainties may cause our actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by any forward-looking statements. When relying on our forward-looking statements to make decisions, investors and others should carefully consider the foregoing factors and other uncertainties and potential events.

Copies of our Canadian public filings are available at www.tescocorp.com and on SEDAR at www.sedar.com. Our U.S. public filings are available at www.tescocorp.com and on EDGAR at www.sec.gov.

Please see Part I, Item 1A—"Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2012 (“2012 Annual Report on Form 10-K”) and Part II, Item 1A—"Risk Factors" of this Quarterly Report on Form 10-Q for further discussion regarding our exposure to risks. Additionally, new risk factors emerge from time to time and it is not possible for us to predict all such factors, nor to assess the impact such factors might have on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

We are a global leader in the design, manufacture, and service delivery of technology-based solutions for the upstream energy industry. We seek to change the way wells are drilled by delivering safer and more efficient solutions that add real value by reducing the costs of drilling for, and producing, oil and natural gas. Our product and service offerings consist mainly of equipment sales and services to drilling contractors and oil and natural gas operating companies throughout the world.

Basis of Presentation

We prepared this Quarterly Report on Form 10-Q pursuant to instructions for quarterly reporting required to be filed with the Securities and Exchange Commission (“SEC”). Because this is an interim period filing presented using a condensed format, it does not include all information and footnotes normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). You should read this report along with our Annual Report on Form 10-K for the year ended December 31, 2012, which contains a summary of our significant accounting policies and other disclosures. The condensed consolidated financial statements as of March 31, 2013 and for the quarters ended March 31, 2013 and 2012 are unaudited. We derived the unaudited condensed consolidated balance sheet as of December 31, 2012 from the audited consolidated balance sheet filed in our 2012 Annual Report on Form 10-K. In our opinion, we have made adjustments, all of which were normal recurring adjustments unless otherwise disclosed herein, that we believe are necessary for a fair statement of the balance sheets, results of operations, and cash flows, as applicable.

These unaudited condensed consolidated financial statements include the accounts of all consolidated subsidiaries after the elimination of all significant intercompany accounts and transactions.

Fair Value of Financial Instruments

At March 31, 2013, the carrying amount of cash and cash equivalents, accounts receivable trade, restricted cash, non-trade receivables, accounts payable, and accrued liabilities approximated their fair value due to their short maturities. At March 31, 2013, the carrying amount of our long term debt approximated its fair value. The fair value of our long term debt is determined using observable inputs and is based on current market interest rates for debt issued with similar maturities by companies with risk profiles similar to ours (Level 2).

Subsequent Events

We conducted our subsequent events review through the date on which these unaudited condensed consolidated financial statements were filed with the SEC.

Note 2—Summary of Significant Accounting Policies

Significant Accounting Policies

There have been no material changes to our accounting policies, as described in the notes to our audited consolidated financial statements included in our 2012 Annual Report on Form 10-K.

Recent Accounting Pronouncements

Each reporting period we consider all newly issued but not yet adopted accounting and reporting guidance applicable to our operations and the preparation of our consolidated financial statements. We do not believe that any issued accounting and reporting guidance not yet adopted by us will have a material impact on our unaudited condensed consolidated financial statements.

Note 3—Sale of Casing Drilling

On June 4, 2012, the Company completed the sale of substantially all of the assets of the Casing Drilling segment to Schlumberger Oilfield Holdings Ltd. and Schlumberger Technology Corporation (together, the "Schlumberger Group") for a total cash consideration of approximately $46.6 million, including a working capital purchase price adjustment. During the three months ended March 31, 2013, the Company recognized a pre-tax gain of approximately $1.5 million primarily from the working capital purchase price adjustment, in addition to the $12.3 million pre-tax gain recognized in 2012, which increased the total pre-tax gain from the sale to $13.8 million, net of transaction costs. The table below sets forth the details contributing to the gain on sale (in thousands):

Note 9—Income Taxes

Tesco Corporation is an Alberta, Canada corporation. We conduct business and are taxed on profits earned in a number of jurisdictions around the world. Income taxes have been recorded based on the laws and rates in effect in the countries in which operations are conducted or in which we are considered a resident for income tax purposes.

Our income tax provision for the three months ended March 31, 2013 and 2012 was as follows (in thousands):

Our effective tax rate, which is income tax expense as a percentage of pre-tax earnings, was 30% for the three months ended March 31, 2013 and the same period in 2012.

At December 31, 2012, we had an accrual for uncertain tax positions of $2.2 million. There was no change to this accrual during the first quarter of 2013, leaving a balance of $2.2 million at March 31, 2013. The accrual for uncertain tax positions is included in accrued and other current liabilities or other liabilities in our consolidated balance sheet based on whether we anticipate the uncertainties to be resolved within the next 12 months. At March 31, 2013, $1.0 million is included in accrued and other current liabilities, and $1.2 million is included in other liabilities. The resolution of these uncertainties should not have a material impact on our effective tax rate.

Certain state and foreign tax filings remain open to examination. We believe that any assessment on these filings will not have a material impact on our financial position, results of operations, or cash flows. We believe that appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years. However, audit outcomes and the timing of audit

settlements are subject to significant uncertainty. Therefore, additional provisions on tax-related matters could be recorded in the future as revised estimates are made or the underlying matters are settled or otherwise resolved.

As part of our acquisition of Premiere Casing Services - Egypt S.A.E ("Premiere") in 2011, we assumed $7.4 million of outstanding debt at the acquisition date of October 16, 2011. During 2012, we paid off a significant amount of the outstanding balances related to Premiere's capital leases and all of the balances related to the notes payable. At March 31, 2013 the outstanding balance of Premiere's capital leases was $0.2 million.

At March 31, 2013, we had a credit agreement which was entered into on April 27, 2012, to provide a revolving line of credit of $125 million, including up to $20 million of swing line loans (collectively, the “Revolver”). The credit facility has a term of five years and all outstanding borrowings on the Revolver are due and payable on April 27, 2017. The credit facility bears interest at a margin above LIBOR, federal funds rate, or the prime rate for U.S. dollar loans as determined by JPMorgan Chase Bank, N.A. in New York. We are required to pay a commitment fee on available, but unused, amounts of the credit facility of 0.375-0.500 percent per annum and a letter of credit fee of 1.00-2.00 percent per annum on outstanding face amounts of letters of credit issued under the credit facility. Amounts available under the Revolver are reduced by letters of credit issued under our credit facility, not to exceed $50 million in the aggregate. Amounts available under the swing line loans may also be reduced by letters of credit or by means of a credit to a general deposit account of the applicable borrower. The availability of future borrowings may also be limited in order to maintain certain financial ratios required under the covenants. The credit facility contains covenants that we consider usual and customary for an agreement of this type, including a leverage ratio, a minimum net worth, and limitations on allowable amounts for the disposal of obsolete assets and annual capital expenditures, and a fixed charge coverage ratio. The credit facility prohibits incurring any additional indebtedness outside the existing credit facility in excess of $50 million, paying cash dividends to shareholders, and contains other restrictions, which are standard to the industry. All of our direct and indirect material subsidiaries in the United States, Canada, Argentina, Mexico, and Indonesia as well as one of our Cyprus subsidiaries are guarantors of any borrowings under the credit facility.

Under the Revolver at March 31, 2013, we had no outstanding borrowings, $4.7 million in letters of credit outstanding and $120.3 million in available borrowing capacity. We were in compliance with our bank covenants at March 31, 2013.

In the normal course of our business, we are subject to legal proceedings brought by or against us and our subsidiaries. None of these proceedings involves a claim for damages exceeding ten percent of our current assets on a consolidated basis. The estimates below represent our best estimates based on consultation with internal and external legal counsel. There can be no assurance as to the eventual outcome or the amount of loss we may suffer as a result of these proceedings.

VARCO Litigation: Varco I/P, Inc. (“Varco”) filed suit against us in April 2005 in the U.S. District Court for the Western District of Louisiana, alleging that our CDS infringes certain of Varco’s U.S. patents. Varco seeks monetary damages and an injunction against further infringement. We filed a countersuit against Varco in June 2005 in the U.S. District Court for the Southern District of Texas, Houston Division seeking invalidation of the Varco patents in question. In July 2006, the Louisiana case was transferred to the federal district court in Houston, and as a result, the issues raised by Varco have been consolidated into a single proceeding in which we are the plaintiff. We also filed a request with the U.S. Patent and Trademark Office (“USPTO”) for reexamination of the patents on which Varco’s claim of infringement is based. The USPTO accepted the Varco patents for reexamination, and the district court stayed the patent litigation pending the outcome of the USPTO reexamination. In May 2009, the USPTO issued a final action rejecting all of the Varco patent claims that we had contested. Varco has appealed this decision with the USPTO and that reexamination appeal is pending. The outcome and amount of any future financial impacts from this litigation are indeterminable at this time.

Weatherford Litigation: Weatherford International, Inc. and Weatherford/Lamb Inc. (together, “Weatherford”) filed suit against us in the U.S. District Court for the Eastern District of Texas, Marshall Division in December 2007 (the “Marshall Suit”), alleging that various of our technologies infringe 11 different patents held by Weatherford. Weatherford sought monetary damages and an injunction against further infringement. Our technologies referred to in the claim included the CDS, the Casing Drilling system and method, a float valve, and the locking mechanism for the controls of the tubular handling system. We filed a general denial seeking a judicial determination that we did not infringe the patents in question and/or that the patents are invalid.

In August 2008, we filed suit against several competitors in the U.S. District Court for the Southern District of Texas – Houston Division, including Weatherford (the “Houston Suit”). The Houston Suit claims infringement of two of our patents related to our CDS. On October 26, 2010, we entered into a settlement with Weatherford (the “Settlement”) dismissing both the Marshall Suit and the Houston Suit (as it relates to Weatherford) with prejudice. Among other provisions, the Settlement contains the following terms:

•

Non-exclusive irrevocable worldwide and royalty free cross licenses with respect to all the patents asserted by Weatherford in the Marshall Case and by us in the Houston Case, as well as certain other U.S. and foreign equivalents and counterparts; and

•

Weatherford has agreed to purchase for five years67% of its worldwide top drive requirements from us, as long as we can meet production requirements, and to designate us as a preferred provider of after-market sales and service for top drives. The prices we charge Weatherford will be equal to or lower than the prices we charge to any other customer of similar volume of purchases and/or services.

We entered into a Final Settlement and License Agreement (the "Settlement Agreement") with Weatherford on January 11, 2011, effective as of October 26, 2010. As an additional condition of the Settlement Agreement, neither we nor Weatherford will pursue any cause of action that might adversely affect the validity or enforceability of each other's patents as listed in the exhibits to the Settlement Agreement, including any causes of action that may arise from the requests for review (“patent re-examinations”) we and Weatherford filed with the USPTO. However, the patent re-examinations already initiated continue with only the respective patent owner corresponding with the USPTO. Ongoing re-examination procedures include the patents owned by us and asserted in the Houston Suit. An oral hearing with the Board of Patent Appeals and Interferences (“BPAI”) at the USPTO occurred August 1, 2012. On November 27, 2012, the BPAI issued a decision in which all of the claims asserted in the Houston Suit were found to be valid in view of the prior art of record in the re-examination proceedings.

On November 11, 2010, we won a jury verdict against National Oilwell Varco, L.P. ("NOV"), Frank's Casing Crew and Rental Tools, Inc. ("Frank's") and Offshore Energy Services, Inc. ("OES") for infringing our U.S. Patent Nos. 7,140,443 and 7,377,324. In that verdict, the jury found that NOV's accused product, the CRT 350, infringes all valid patent claims in the asserted patents, and that NOV contributorily infringed all valid patent claims in the asserted patents. The jury also found that Frank's accused products,

the (i) SuperTAWG, (ii) FA-1, and (iii) CRT 350, and OES's accused products, the CRT 350, infringe all valid patent claims in the asserted patents. Damages were stipulated by the parties and the verdict is subject to entry of judgment and appeal.

On December 6, 2012, the District Court ruled on summary judgment that all of the asserted patent claims were obvious in view of prior art based on pre-trial evidence. This ruling overturns the favorable jury verdict. We filed a Notice of Appeal on December 21, 2012 seeking to reverse the District Court's ruling. At a procedural hearing on April 2, 2013, the District Court informed the parties that it did not intend for the December 6th Order to be final. The District Court sent a letter to the Court of Appeals for the Federal Circuit on April 12, 2013 to confirm the District Court has jurisdiction “to proceed to set a schedule on discovery, briefing, and a bench trial on inequitable conduct.”

Tax Disputes: We have been previously advised by the Mexican tax authorities that they believe significant expenses incurred by our Mexican operations from 1996 through 2002 are not deductible for Mexican tax purposes. Between 2002 and 2008, formal reassessments disallowing these deductions were issued for each of these years, all of which we appealed to the Mexican court system. We have obtained final court rulings deciding all years in dispute in our favor, except for (i) 1996, as discussed below, and (ii) 2001 and 2002, both of which are currently before the Mexican Tax Court. The outcomes of such appeals are uncertain. We continue to believe that the basis for these reassessments was incorrect, and that the ultimate resolution of those outstanding matters will likely not have a material adverse effect on our consolidated financial position, results of operations, or cash flows.

In May 2002, we paid a deposit of $3.3 million to the Mexican tax authorities in order to appeal the reassessment for 1996. In 2007, we requested and received a refund of approximately $3.7 million (the original deposit amount of $3.3 million plus $0.4 million in interest). With the return of the $3.3 million deposit, the Mexican tax authorities issued a resolution indicating that we were owed an additional $3.4 million in interest and inflation adjustments but this amount had been retained by the tax authorities to satisfy a second reassessment for 1996. We believed the second reassessment was invalid, and appealed it to the Mexican Tax Court. In 2009, the Mexican Tax Court issued a decision accepting our arguments in part, which was subject to further appeal.

In May 2011, we received a refund of approximately $3.8 million (the remaining $3.4 million noted above, plus $0.4 million of additional interest and inflation adjustments) and recorded $2.4 million in interest income, $0.6 million in other income, partially offset by $0.4 million of related interest expense. The remaining $1.2 million is included in other liabilities pending the ultimate resolution of this issue.

In July 2006, we received a claim for withholding tax, penalties and interest related to payments over the periods from 2000 to 2004 in a foreign jurisdiction. We disagreed with this claim and litigated this matter. During 2006, we accrued an estimated pre-tax exposure of $3.8 million and continued to accrue interest for this matter. In April 2012, we received final determination for the 2000 and 2002 tax years and have reversed $1.9 million of the accrual ($1.3 million to other income and a $0.6 million reduction of interest expense). In January 2013, we received final determination for the portion of the claim related to this accrual and have reversed $2.8 million of the accrual ($1.8 million to other income and a $1.0 million reduction of interest expense). At March 31, 2013, we have no accrual remaining for this claim.

In August 2008, we received a claim in Mexico for $1.1 million in fines and penalties related to the exportation of certain temporarily imported equipment that remained in Mexico beyond the authorized time limit for its return. We disagree with this claim and are currently litigating the matter. In December 2009, we received a decision from the Mexican Tax Court in our favor, which is subject to further appeal. The outcome of this litigation is uncertain. No accrual has been recorded for this claim.

Other Contingencies

We are contingently liable under letters of credit and similar instruments that we enter into in connection with the importation of equipment to foreign countries and to secure our performance on certain contracts. At March 31, 2013 and December 31, 2012, our total exposure under outstanding letters of credit was $8.1 million and $8.7 million, respectively.

Note 12—Segment Information

Business Segments

Prior to the sale of the Casing Drilling business during the second quarter of 2012, our four business segments were: Top Drive, Tubular Services, Casing Drilling, and Research and Engineering. On June 4, 2012, the Company completed the sale of substantially all of the assets of the Casing Drilling segment, which consisted of the proprietary Casing Drilling technology. Our Top Drive segment is comprised of top drive sales, top drive rentals, and after-market sales and service. Our Tubular Services segment includes both our proprietary and conventional tubular services. Our Research and Engineering segment is comprised

of our internal research and development activities related to our proprietary tubular services and top drive model development, as well as the Casing Drilling technology prior to the sale.

We measure the results of our business segments using, among other measures, each segment’s operating income, which includes certain corporate overhead allocations. Overhead costs include field administration and operations support. At a business segment level, we incur costs directly and indirectly associated with revenue. Direct costs include expenditures specifically incurred for the generation of revenue, such as personnel costs on location or transportation, maintenance and repair, and depreciation of our revenue-generating equipment.

Certain sales and marketing activities, financing activities, corporate general and administrative expenses, other (income) expense, and income taxes are not allocated to our business segments.

Goodwill is allocated to the business segment to which it specifically relates. Our goodwill has been allocated to the Tubular Services segment.

We attribute revenue to geographic regions based on the location of the customer. Generally, for service activities, this will be the region in which the service activity occurs. For equipment sales, this will be the region in which the sale transaction is complete and title transfers. Our revenue by geographic area for the three months ended March 31, 2013 and 2012 was as follows (in thousands):

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of financial condition and results of operations should be read in conjunction with the unaudited condensed consolidated financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements. Please see “Caution Regarding Forward-Looking Information; Risk Factors” above and “Risk Factors” in Part II, Item IA below and in our 2012 Annual Report on Form 10-K, for a discussion of the uncertainties, risks, and assumptions associated with these statements.

Overview and Outlook

We are a global leader in the design, manufacture and service delivery of technology based solutions for the upstream energy industry. We seek to change the way wells are drilled by delivering safer and more efficient solutions that add real value by reducing the costs of drilling for and producing oil and natural gas.

Prior to the sale of the Casing Drilling business during the second quarter of 2012, our business segments were:

•

Top Drives – top drive sales, top drive rentals, and after-market sales and services;

•

Tubular Services – proprietary and conventional tubular services;

•

Casing Drilling – proprietary Casing Drilling technology; and

•

Research and Engineering – internal research and development activities related to our proprietary tubular services and top drive model development, as well as the Casing Drilling technology prior to the sale.

On June 4, 2012, we completed the sale of substantially all of the assets of our Casing Drilling segment to the Schlumberger Group. For a detailed discussion of this matter, see Part I, Item 1—"Financial Statements", Note 3—Sale of Casing Drilling in this Quarterly Report on Form 10-Q.

Business Environment

One of the key indicators of our business is the number of active drilling rigs. During the first quarter of 2013, North America continued to experience a downturn in rig activity. Europe has been experiencing uncertainty since 2012 over the outcome of the European Union's ("EU") financial support programs for EU member states experiencing financial troubles. The financial troubles of EU member states have created uncertainty and make any projection in Europe difficult. Additionally, certain countries in Latin America experienced a decline in rig activity due to various geopolitical and economic reasons. Current global macro economic conditions make any projections difficult. Below is a table that shows average rig count by region for the three months ended March 31, 2013 and 2012.

Summary of the Quarter Ended March 31, 2013 and Operational Performance

During the first quarter of 2013, our Top Drive segment had 24 top drive units sold compared to 39 during the same period in 2012. Our Tubular Services segment revenue and operating income improved significantly in the first quarter of 2013 as compared to the first quarter of 2012. Our automated tubular services offering continues to gain market acceptance, and we remain

committed to growing this segment as we believe that every rig with a top drive will eventually convert to running casing with an automated system, such as our CDS™ system. We also invested in new and enhanced product and service offerings in our Research and Engineering segment.

Outlook for 2013

The current outlook for the global economy varies widely, but we believe that most indicators point towards a continued slow recovery during the remainder of 2013. Current global macro-economic conditions make any projections difficult and uncertain; however, in each of our revenue generating segments, we anticipate moderately improved activity for the remainder of 2013, as follows:

•

Top Drive - Based upon existing drilling and bidding levels and the size of our product sale backlog, we expect our top drive order rate and rental activity to remain steady for the remainder of 2013. In North America, we continue to experience downward pressure in bidding activity. Our Top Drive sales backlog was 20 units at March 31, 2013, compared to 57 units at March 31, 2012 and 28 units at December 31, 2012. Our customers have maintained their focus on lowering project costs, which continues to put downward pressure on our sales prices on select product offerings. We expect our international top drive sales and rental activity and after-market sales and services to hold steady for the remainder of 2013.

•

Tubular Services - We expect our CDS™ automated and conventional casing running business to strengthen in our international markets for the remainder of 2013. We will continue to expand our automated casing service offerings, particularly in the major unconventional shale regions in North America and select international locations. In addition, we expect drilling activity in the U.S. Gulf of Mexico to gradually increase for the remainder of 2013, which should increase demand for our MCLRS proprietary services.

Our Top Drive business segment sells equipment and provides services to drilling contractors and oil and natural gas operating companies throughout the world. We primarily manufacture top drives that are used in drilling operations to rotate the drill string while suspended from the derrick above the rig floor. We also provide top drive rental services on a day-rate basis for land and offshore drilling rigs, and we provide after-market sales and support for our customers. Below is a summary of our Top Drive operating results and metrics for the three months ended March 31, 2013 and 2012 (in thousands, except percentages, units, days, and rate):

(a) Defined as a day that a unit in our rental fleet is under contract and operating; does not include stand-by days.

Top Drive operating results were largely driven by oil and natural gas drilling activity and new rig build activity. The average active rig count decreased by 5% in the first quarter of 2013 from the same period in 2012.

Top Drive sales revenue — The decrease in revenue for the three months ended March 31, 2013 compared to the same period in 2012 was due to fewer units sold as a result of decreased demand, both domestically and internationally.

The selling price per unit varies significantly depending on the model, whether the unit was previously operated in our rental fleet and whether a power unit was included in the sale. Revenue related to the sale of used or consignment top drive units was $1.7 million and $7.0 million for the three months ended March 31, 2013 and 2012, respectively.

Top Drive rental revenue — The decrease in revenue for the three months ended March 31, 2013 compared to the same period in 2012 was due to decreased operating days as a result of lower rig count in North America.

Top Drive after-market sales and services revenue — The decrease in revenue for the three months ended March 31, 2013 as compared to the same period in 2012 was due to decreased demand in North America.

Top Drive operating income — The decrease in operating income for the three months ended March 31, 2013 as compared to the same period in 2012 was due to decreases in sales, rental and after-market sales and services revenue discussed above. During the first quarter of 2012, our quality control processes found casting anomalies in the gearbox housing of our new ESI top drive model and subsequently determined that the casting of the gearbox housing did not meet TESCO's standards. We recorded warranty expenses of $3.9 million during the first quarter of 2012 specifically associated with this ESI gearbox housing issue.

Our Tubular Services business segment includes both automated and conventional services, which are typically offered as a “call out” service on a well-by-well basis. Our automated service offerings, in particular the CDS™, provide a safer and more automated method for running casing and, if required, reaming the casing into the hole, as compared to traditional methods. Additionally, our automated Tubular Service business includes the installation services of deep water smart well completion equipment using our MCLRS, a proprietary and patented technology that improves the quality of the installation of high-end well completions. Our conventional Tubular Service business provides equipment and personnel for the installation of tubing and casing, including power tongs, pick-up/lay-down units, torque monitoring services, and connection testing services for new well construction and in work-over and re-entry operations. Below is a summary of our Tubular Services operating results and metrics for the three months ended March 31, 2013 and 2012 (in thousands, except percentages and number of jobs):

The increase in Tubular Services revenue for the three months ended March 31, 2013 compared to the same period in 2012 was due to increased demand in the Asia Pacific region, North America, and Latin America for automated offerings, and the Middle East for conventional offerings. A significant amount of current U.S. drilling activity is in shale formations that require directional and horizontal drilling techniques, which we believe are good applications for our automated service offerings. In addition, increased domestic and international demand for our tubular services, both automated and conventional, has resulted in new jobs at more favorable pricing terms. During the three months ended March 31, 2013, we recorded $1.7 million of revenue from our MCLRS™ offerings, compared to $0.9 million during the same period in 2012. The Tubular Services automated revenue during the three months ended March 31, 2013 and 2012 also included $2.8 million and $1.8 million, respectively, of revenue for CDS™ equipment sales.

The increase in Tubular Services operating income for the three months ended March 31, 2013 as compared to the same period in 2012 was due to higher revenue discussed above, including higher MCLRS™ and CDS™ equipment sales revenue, which provide higher operating margins.

Casing Drilling Segment

On June 4, 2012, we completed the sale of substantially all of the assets of our Casing Drilling segment to the Schlumberger Group. The Casing Drilling business was based on the proprietary Casing Drilling technology, which used patented equipment and processes to allow an oil or gas well to be drilled using standard well casing pipe.

Below is a summary of the operating results of the segment prior to the sale for the three months ended March 31, 2013 and 2012 (in thousands, except percentages):

Casing Drilling operating income for the three months ended March 31, 2013 was primarily attributed to a working capital adjustment gain of approximately $1.5 million from the sale. For a detailed discussion of this matter, see Part I, Item 1—"Financial Statements", Note 3—Sale of Casing Drilling in this Quarterly Report on Form 10-Q.

Research and Engineering Segment

Our Research and Engineering segment is comprised of our internal research and development activities related to our automated Tubular Services and top drive model development, as well as the Casing Drilling technology prior to the sale. Below is a summary of our research and engineering expense for the three months ended March 31, 2013 and 2012 (in thousands, except percentages):

Research and engineering expenses decreased during the three months ended March 31, 2013 as compared to the same periods in 2012 due to the termination of Casing Drilling research and engineering after the sale of this business on June 4, 2012. We continue to invest in the development, commercialization, and enhancements of our proprietary technologies relating to our Top Drive and Tubular Services segments.

Corporate and Other Segment

Corporate and other expenses primarily consist of the corporate level general and administrative expenses and certain selling and marketing expenses. Below is a summary of our corporate and other expenses for the three months ended March 31, 2013 and 2012 (in thousands, except percentages):

Corporate and other expenses were higher during the three months ended March 31, 2013, as compared to the same period in 2012 due primarily to increased short term and long term incentive compensation and payroll and benefit expense from increased headcount for operations support personnel.

Other Expense (Income)

Below is a summary of our other expense (income) for the three months ended March 31, 2013 and 2012 (in thousands, except percentages):

In April 2012, we received a favorable determination on a legacy withholding tax issue in a foreign jurisdiction. The impact of this was recognized in the first quarter of 2012, when we reversed $1.9 million of accruals previously made for this issue (consisting of $1.3 million to other income and a $0.6 million reduction of interest expense). For a detailed discussion of this matter, see Part I, Item 1—"Financial Statements", Note 11—Commitments and Contingencies in this Quarterly Report on Form 10-Q.

Foreign exchange losses increased during the three months ended March 31, 2013 as compared to the same periods in 2012 due primarily to the devaluation of the Venezuelan Bolivar Fuerte in February 2013 as well as fluctuations in the valuation of the U.S. dollar compared to other currencies we transact in around the world, including the Argentine peso, Mexican peso, and Russian ruble, among others.

We are an Alberta, Canada corporation. We conduct business and are taxed on profits earned in a number of jurisdictions around the world. Our income tax rate is based on the laws and rates in effect in the countries in which our operations are conducted or in which we are considered a resident for income tax purposes. Our effective tax rate, which is income tax expense as a percentage of pre-tax earnings, did not change for the three months ended March 31, 2013 compared to the same period in 2012.

Liquidity and Capital Resources

We rely on our cash and access to credit to fund our operations, growth initiatives and acquisitions. Our primary sources of liquidity are cash flows generated from our operations, available cash and cash equivalents, and available borrowings under our revolving credit facility. We use these sources of liquidity to fund our working capital requirements, capital expenditures, strategic investments and acquisitions. For 2013, we forecast capital expenditures to be between $30 million and $40 million based on expected demand for our products and services. We expect to be able to fund our activities for 2013 with cash flows generated from our operations, available cash and cash equivalents, and available borrowings under our revolving credit facility.

As of March 31, 2013, we had no outstanding borrowings under our revolving credit facility, and we had availability to borrow $120.3 million under our revolving credit facility. The availability of current borrowings is, and future borrowings may be, limited in order to maintain certain financial ratios required by restrictive covenants in our credit facility. We were in compliance with our bank covenants at March 31, 2013. For further discussion on our credit facility, see Part I, Item 1—“Financial Statements”, Note 10 of this Quarterly Report on Form 10-Q.

We report our net cash position because we regularly review it as a measure of our performance. However, the measure presented in this Quarterly Report on Form 10-Q may not always be comparable to similarly titled measures reported by other companies due to differences in the components of the measurement we use.

Cash Flows

Our cash flows fluctuate with the level of spending by oil and natural gas companies for drilling activities. Certain sources and uses of cash, such as the level of discretionary capital expenditures and the issuance and repayment of debt, are within our

control and are adjusted as necessary based on market conditions. The following is a discussion of our cash flows for the three months ended March 31, 2013 and 2012.

Operating Activities – Net cash provided by operating activities is our primary source of capital and liquidity. Net cash provided by operating activities was $8.0 million for the three months ended March 31, 2013 compared to net cash used of $8.0 million for the same period in 2012. The increase in net cash provided by operating activities was due primarily cash inlays from decreasing accounts receivable and decreased cash outlay for inventory purchases.

Investing Activities – Net cash used by investing activities was $4.9 million during the three months ended March 31, 2013 compared to $17.0 million used during the same period of 2012. During the three months ended March 31, 2013 and 2012, we used $9.0 million and $17.9 million of cash, respectively, for capital expenditures, and sales of operating assets provided $1.9 million and $0.8 million of cash, respectively. Additionally for the three months ended March 31, 2013, we received $1.6 million of cash from the sale of Casing Drilling segment to the Schlumberger Group.

Financing Activities – Net cash provided by financing activities was $0.1 million during the three months ended March 31, 2013 compared to $19.8 million for the same period in 2012. During the three months ended March 31, 2012, we borrowed $26.0 million from our revolving credit facility and used $6.3 million of cash to repay our debt.

Manufacturing Purchase Commitments

Our manufacturing purchase commitments, which represent executed purchase orders that have been submitted to the respective vendors, have increased from $34.9 million as of December 31, 2012 to $38.2 million as of March 31, 2013. This increase of $3.3 million, or 9%, is driven by the anticipated demand for our CDS™ equipment and after-market part sales.

Off-Balance Sheet Arrangements

As of March 31, 2013, we have no off-balance sheet arrangements other than the manufacturing purchase commitments and letters of credit described above, and future interest payments on the aggregate unused commitments under our revolving credit facility and lease commitments as described in Part II, Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2012 Annual Report on Form 10-K.

Critical Accounting Estimates and Policies

Our accounting policies are described in the notes to our audited consolidated financial statements included in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2012 Annual Report on Form 10−K. We prepare our unaudited condensed consolidated financial statements in conformity with U.S. GAAP. Our results of operations and financial condition, as reflected in our unaudited condensed consolidated financial statements and related notes, are subject to management’s evaluation and interpretation of business conditions, changing capital market conditions and other factors that could affect the ongoing viability of our business and customers. We believe that the most critical accounting policies in this regard are those described in our 2012 Annual Report on Form 10−K. While these issues require us to make judgments that are subjective, they are generally based on a significant amount of historical data and current market data. There have been no material changes or developments in authoritative accounting pronouncements or in our evaluation of the accounting estimates and the underlying assumptions or methodologies that we believe to be critical accounting policies and estimates as disclosed in our 2012 Annual Report on Form 10−K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

See Part I, Item 7A —“Quantitative and Qualitative Disclosures About Market Risk” in our 2012 Annual Report on Form 10-K for a detailed discussion of the risk factors affecting us. There have been no material changes to the market risk described in Part I, Item 7A —"Quantitative and Qualitative Disclosures About Market Risk" disclosed in our 2012 Annual Report on Form 10-K.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in the SEC reports we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized, and reported within the time period specified by the SEC’s rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. As of March 31, 2013, our Chief Executive Officer and Chief Financial Officer participated with management in evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act). Our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2013, our disclosure controls and procedures were effective at the reasonable assurance level.

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2013, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

In the normal course of our business, we are subject to legal proceedings brought by or against us and our subsidiaries. None of these proceedings involves a claim for damages exceeding ten percent of our current assets on a consolidated basis. See Part I, Item 1—“Financial Statements”, Note 11 of this Quarterly Report on Form 10-Q for a summary of certain ongoing legal proceedings. Such information is incorporated into this Part II, Item 1—"Legal Proceedings" by reference.

On December 26, 2012, we received a request by the staff of the United States Securities and Exchange Commission ("SEC") that the Company take steps to preserve and retain five categories of documents relating to commercial agents who perform services for the corporate group in a foreign jurisdiction, the Company's general use of commercial agents in that jurisdiction, and compliance with the Foreign Corrupt Practices Act. This request stated that it "should not be construed as an indication by the Commission, or its staff, that any violations of law have occurred; nor should it be considered an adverse reflection upon any person, entity, or security." We have, under the advice and through independent external legal counsel, cooperated with and have provided the SEC staff with specific information which it has requested. External legal counsel for the Company has been advised by the SEC staff that no formal order of investigation has been issued. The outcome of the SEC's review and any future financial impact resulting from this matter are indeterminable at this time.

Item 1A. Risk Factors.

See Part I, Item 1A—"Risk Factors" in our 2012 Annual Report on Form 10-K for a detailed discussion of the risk factors affecting us. There have been no material changes to the risk factors described in Part I, Item 1A—"Risk Factors" disclosed in our 2012 Annual Report on Form 10-K.
